WASTE VALVE FOR SANITARY APPLIANCES.

Application filed October 7, 1925.

My invention relates to waste valves which are adapted for use in connection with sanitary appliances such as bath tubs, basins and the like.

The general object of the invention is to provide a novel construction of valve with means for opening and closing the same which is compact and in effect self-containmg.

It is also an object of the invention to provide a valve which may be installed or placed in position in constructions already in use with a minimum of change or alteration.

Another object of the invention is to provide means located directly underneath the valve element for actuating the latter, the said means being actuated by means located directly above the said valve element.

A further object of the invention is to provide a waste valve for sanitary appliances in which the valve element is adapted to be supported upon levers located within and near the top of the outlet to be controlled, which levers are adapted to be actuated for opening and closing the said valve by means associated with the said valve.

To these and other ends the invention comprehends the construction and arrangement of parts as hereinafter described in detail, particularly pointed out in the claims, and as illustrated in the drawing in which I have shown a convenient form of mechanical embodiment of the said invention.

It will be understood that the invention is susceptible of embodiment in other forms of construction than that shown and that changes in the details of construction may be made within the scope of the claims without departing from the principle thereof.

In the drawing:

Fig. 1 is a central vertical section through the upper end portion of a conduit provided with a valve structure embodying the invention, the said valve being in closed posi tion;

Serial No. 60,952.

Fig. 4 is a vertical sectional view through the valve structure alone taken on the line 44 of Fig. 1; i

Fig. 5 is a top plan View of the valve in position for controlling the outlet of a bath tub or the like; and

Fig. 6 is a perspective view of one of the levers by means of which the valve element of the structure is adapted to be opened and closed.

Referring to the drawing: 1 designates the upper portion of a soil pipe leading from a bath tub or other structure, a portion of the bottom of which is indicated at 2. The upper end of the soil pipe 1 is provided with a laterally extending flange 3 which is located underneath and in adjacent relaticn to the under side of a portion of the part 2 of the bath tub or other appliance surrounding an opening t therein. The upper end of the soil pipe 1 and the flange 3 are clamped against a washer 5 underneath the portion of the bottom 2 surrounding the opening 4 by means of a screw threaded coupling device or member 6 having a flange 7 which'overlies the inner edge portion of the part 2 surrounding the opening 1. The coupling 01 the upper end of a waste or soil pipe to a bath tub, basin or the like in this manner is quite well known. The inner upper edge of the securing and coupling member 6 is beveled, as indicated at 10, to form a seat for the outer beveled edge of a valve 11. Bars 12 are connected at intervals at their upper ends to the valve 11 near its outer edge. These bars extend downwardly into the coupling member 6 and are engaged at their lower ends by a ring member 13. The valve 11, bars 12 and ring member 13 may be formed integrally, or the said bars may be rigidly connected in any other preferred manner. A couple of downwardly extending projections 15 are secured to the lower end of a may be formed integrally with each other and may be also formed integrally with the member 6, or they may be otherwise connected, as may be preferred. The bar '16 is provided with upwardly extending projections 17 spaced apart, as indicated,- to form a guide for a head 18 upon the lower end of a manually operable member 19. The portion 19 of the said manually operable member is of reduced size as compared with the head 18 and extends upwardly through an opening 20 in the valve member 11. The head is provided with a slot, as

indicated at 22, into which project the inner ends of levers 2 3 which levers extend outwardly bet-ween the projections 17, which are arranged in coup es, and are mounted upon-pivots '25 through the said projections. The outerends'of the said levers terminate 'at points or positions underneath the ring member '13 previously referred to; The inner ends of the levers arenotched, as indicated at 26, andoverlap each other as shown in the drawing; These overlapped end"portions are" rovided with slots 27 through which a pin 30 extends the 'oppo site ends of which are secured in holes in the portions ofthe head 18 upon opposite sides of the slot22.

"The upper end portion of the manually operable device 19 isprovided with a disk member 31' which operates to prevent accidental removal of't-he'valve member 11 from its position upon the member 19, and also operates means for renderingmore convenient the manualoperation of the said member 19 to o erate'the levels 23 to open andclosethe val ve 1.1. Vhc'n in open position the disk member 31 occupies a position within the depression3 5 of the valve with its top surface flush with the top surface of the outer edge or rim'portions of the said valve." "As indicated in" the drawing, the disk member 31 is detachable or removable from the stem member 19. Upon such'remov'al the valve 11 may be removed thereby providing free access tothe levers 23 and other parts of the'structure which normany are" underneath the valve in order that" any repairs thereto may be facilitated. By reason of such access the cleaning of the portion "of the structure underneath the valve is also facilitated;

'YVhen thevalve ll is in open position as shown inFig. 2, i'ts tendency due to gravity is us close. Such closing is resisted not only by suc'hback pressure 'as may be due'to water'or air; or both, within the waste pipe, but also by the 'w'eights of the manually operable member including the parts 18, 19 and 31'and' the inner end portions of the levers 23. It is apparent that the shorter the leverage between the points of contact oi? the outer ends of the levers 23 with the ring member 13 when the valve is in open position, the greater security will there be against accidental closing of the valve due to its weight. ln order, therefore, to provide a construction in which when once opened the valve will remain open, I have located the pivots 25 for the levers 23 as near to the outer ends of the latter as seems to be practical. tlowever, it will be understood that my invention is not limited to the particular place of location of the pivots 25. Practically, however, said pivots should be located as near to the outer ends of the levers as may be possible.

will be noted'thatthe outer edge portions of the projections 17 serve as additional guides for guiding'the opening and clos-ii-ng i iovemen'ts of the valve.

It villhe seen that by my invention I have provided a valve structure which is compact and in which the valve and operative pa'rts are all located practically within the open upper end oi the waste pi e through which water is adapted to be discharged from a bath tub, basin or other sanitary appliance or fixture. By providing a structure with the parts thereof arranged in compactrelation to each other and in the position as stated I am'enabled to avoid the o't'operat Jeans at some point a .7 from t. the bath tub, basin orother fixture, and which usually involves operative mechanism more or less complicated in character.
